Highways, these human-built roads for wild animals, is likely to be their "life and death line", will lead to many animals will be hit, or hinder their survival and reproduction, so whether wild animals can safely cross the road has become a concern, many countries and places began to build safe passages for wild animals, of which Australia for tens of millions of red crabs to build a special passage - red crab bridge, is one of the most famous wildlife safety channels!
Red crab, also known as Christmas Island red crab, is a species endemic to Australia, only distributed in Australia Christmas Island, the width of the shell of the red crab is about 11.5 cm, the shape of a roasted lobster, the external color is red, in addition to the back shell is black, the abdomen and limbs are red, especially during the Great Migration, the crab population looks red from a distance.
Red crabs, like some retrospective fish, during the breeding season, as a land crab on the island, need to go to the ocean to spawn and breed offspring, which is a marine crab. So christmas island red crabs at the end of October every year, began to make a large-scale trek, to return to the ocean to breed offspring, tens of millions of red crabs to go through various roads, railways, etc., the direction of the direction is not signposted, they all rely on the feeling of the temperature of the sea to identify the direction.
In the process of the red crab migration, especially when crossing the road, a car passing, will inevitably cause a large number of casualties, in order to protect these unique species, to avoid vehicles crushing the red crab group, the local staff will "block" the red crab must pass the road in advance, set up some roadblocks, prevent them from crawling to the middle of the road, and build a 5-meter-high overpass and many underground passages, providing extremely convenient travel conditions for this group of red crabs.
This overpass is densely covered with red crabs, which looks like a red bridge from a distance, so it is called the Red Crab Bridge, and this loving bridge has slowly become a famous tourist attraction and attracted many tourists to come to see. In fact, the local government will even close roads and railways during the red crab breeding season, especially during the 5-7 day migration peak, and even which road will be blocked depends entirely on the route of the red crab migration, just to protect the red crab crossing the road!
The construction of the red crab bridge is a harmonious and friendly coexistence between humans and animals, the red crab passes on the overpass above, the vehicle passes on the road below, they do not disturb each other and help each other, the red crab avoids injury, and the vehicle also avoids accidents, but also helps humans themselves, so more and more countries will build some wildlife safety passages in order to better protect animals!
Red crabs are unique to Australia's Christmas Island, they also have an important role in the ecology of Christmas Island, these red crabs hide in the bushes, often digging burrows at the roots of trees, but their excrement is an important rainforest fertilizer, and the act of digging holes will also play a role in turning the soil and helping to ventilate the soil!
Pay attention to the six dimensions of nature And let nature know nature!
